Description

This pull request introduces the GetAllUserPostUseCase class to the application layer.
Its primary function is to retrieve all posts associated with a given user ID, using the GetAllUserPostQueryServiceInterface, and return them as a paginated result.

Details:

• Introduced GetAllUserPostUseCase with method handle(int $userId, int $perPage, int $currentPage): Pagination
• Delegates actual data retrieval to the query service
• Keeps application logic clean and focused on orchestration
